The invention relates to the refrigerating engineering, in particular to the throttling devices. The dirigible throttling device includes a hollow cylindrical body with inlet and outlet ports, an electromagnetic coil placed onto the body lateral outside, a mobile ferromagnetic element, placed into the body cavity, a heat-sensing device and a control unit. Novelty of the invention consists in that into both bases of the body there are placed limiting grids, between which there is placed the mobile ferromagnetic element, formed of an aggregate of ferromagnetic particles. The body is divided into two zones: a zone with greater internal diameter from the end of the inlet port and a zone with smaller internal diameter from the end of the outlet port. The throttling device contains an additional electromagnetic coil, placed onto the body lateral outside above the zone with smaller internal diameter. Inventia se refera la tehnica frigorifica, in particular la dispozitive de laminare. Dispozitivul de laminare dirijabil include un corp cilindric cavcu canale de intrare si iesire, o bobina electromagnetica amplasata pe partea laterala exterioara acorpului, un element feromagnetic mobil, amplasatin cavitatea corpului, un traductor termic si un bloc de dirijare. Noutatea inventiei consta in aceea ca in ambele baze ale corpului sunt fixate plase limitatoare, intre care este amplasat elementul feromagnetic mobil, format dintr-un agregat de particule feromagnetice. Corpul este divizat in doua zone: o zona cu diametrul interior mare de partea canalului de intrare si o zona cu diametrul interior mic de partea canalului de iesire. Dispozitivulde laminare contine o bobina electromagnetica suplimentara, amplasata pe partea laterala exterioaraa corpului deasupra zonei cu diametrul interior mic.
